Objective: To statistically analyze the association between blood donation intervals and the incidence of adverse reactions to blood donation based on blood donor data from Shenzhen. Methods: Basic data and records of adverse reactions to blood donation among voluntary whole blood donors in Shenzhen from January 2017 to June 2025 were extracted. A total of 795 404 whole blood donations were recorded, including 502 743 from males and 292 661 from females, with 1 088 and 751 cases of adverse reactions, respectively. Analyses were performed using R software, including restricted cubic spline (RCS), binary logistic regression, and generalized estimating equations (GEE) to evaluate the correlation between donation intervals and adverse reactions. Results: A total of 1 839 cases of adverse reactions were recorded, accounting for 0.23% of the total donations. Both binary logistic regression analysis and the generalized estimating equations (GEE) model showed that there was no significant difference in the incidence of adverse reactions between male and female donors with an interval of ≥6 months compared to those with an interval of ≥3 months but<6 months. Furthermore, using the 3-5 month interval group as the reference, the analysis indicated that the incidence of adverse reactions significantly increased in males with a 9-12 month interval, while no statistically significant differences were observed across any of the female subgroups. Conclusion: There was no significant correlation between adverse reactions to blood donation and the donation interval. Compared with a donation interval of ≥6 months, an interval of<6 months does not lead to an increase in the incidence of adverse reactions among male or female donors. The findings of this study may help enhance the willingness of blood donors to participate.

Objective: To statistically analyze the association between blood donor age and the incidence of adverse reactions based on whole blood donor data from Shenzhen. Methods: Data on basic characteristics and records of adverse donation reactions among voluntary whole blood donors in Shenzhen from January 2017 to June 2025 were extracted. A total of 795 404 whole blood donations were recorded, including 502 743 from males and 292 661 from females, with 1 088 and 751 cases of adverse reactions, respectively. Analyses were performed using R software, including restricted cubic spline (RCS) analysis, binary logistic regression, and generalized estimating equations (GEE) to evaluate the correlation between donor age and adverse reactions. Results: A total of 1 839 cases of adverse reactions were recorded, accounting for 0.23% of the total donations. Both binary logistic regression and GEE model revealed that, compared with the≤55 years age group, the incidence of adverse reactions was reduced in both male and female donors in the >55 years age group, with the difference being statistically significant in males. Using the <23 years age group as a reference, the incidence of adverse reactions significantly decreased in both male and female donors across the 23-30, 31-40, 41-50, and 51-60 age groups, with the differences being statistically significant. Conclusion: There is a negative correlation between the rate of adverse donation reactions and age, with the incidence of such reactions among whole blood donors over 55 years old being no higher than that among donors aged 55 years or younger. These findings carry positive significance for safeguarding the donation rights of older donors and meeting clinical blood demand.

Objective: To construct a 5G unmanned aerial vehicle (UAV) airport platform for blood transportation and explore its feasibility and advantages within the blood emergency support system. Methods: Based on 5G high-speed network transmission technology, a UAV management system was designed to achieve a closed-loop management of the entire transportation process, including blood distribution, route information, flight status, emergency dispatch, hospital reception, real-time temperature monitoring, and video surveillance. Integrated with an open UAV airport, the first "5G UAV Blood Transportation Intelligent Airport Platform" was established. Results: At present, the platform has settled in 2 sets of UAV systems, established 17 routes, and carried out regular UAV blood transportation services for 15 hospitals. From January 1, 2024 to June 30, 2025, a total of 12 134 sorties were completed, with a total transported blood weight of 7 692.38 kg, including 25 500 units of red blood cells, 3 824.5 units of platelets, 1 350 370 mL of plasma, and 10 810 units of cryoprecipitate. Compared to land transportation, UAV delivery saved an average of 46.8 minutes during rush hours (maximum: 89.3 minutes) and an average of 32.3 minutes during non-rush hours (maximum: 59.1 minutes). In terms of the quality of UAV blood transportation, the temperature of suspended red blood cells was between 4 and 8℃, that of platelets was between 20 and 24℃, and that of plasma was below 0℃. No damage has occurred so far. Conclusion: The UAV blood transportation platform can stably provide blood delivery services during both routine and emergency conditions, ensuring timely blood delivery and stable blood quality.

【Objective】 To establish and improve the emergency recruitment strategy of voluntary blood donors under public health emergencies in Shenzhen and verify its effectiveness. 【Methods】 Blood donor recruitment strategies under routine, emergency and combined situation were developed. The blood collection data from 2017 to 2019 before the outbreak of COVID-19 pandemic was used as the control group, and those from 2020 to 2022 after the outbreak was used as the experimental group, and the feasibility and effectiveness of this emergency recruitment strategy was confirmed through statistical analysis of key indicators of blood collection and supply. 【Results】 Through the application of the emergency recruitment strategy for blood donors in Shenzhen under public health emergencies, statistical analysis of the experimental group and the control group showed a year-on-year increase of 14.11%(73 647.25/521 855.5) in whole blood collection, 42.33%(28 891.47/68 250.95) in platelet collection, 0.33%(529/161 033) in first-time donors, 33.25%(3 154/9 487) in repeated donors and 16.78%(32 585/194 149) in the number of 400 mL donors. The inventory of various types of red blood cell maintained between 6-18 days. After the implementation of the emergency recruitment strategy the blood donation population has shown characteristics as younger age, localization, increased repeated donation and a higher proportion of donors with college education or above. 【Conclusion】 The emergency recruitment strategy of blood donors under public health emergencies is feasible and effective, which can quickly and efficiently improve the blood recruitment ability.

OBJECTIVE:To explore the role of clinical pharmacists on pharmaceutical care for allergic reaction caused by ox-aliplatin. METHODS:Clinical pharmacists conducted pharmaceutical care for a patient with oxaliplatin-induced allergic reaction, and suggested stopping taking oxaliplatin,giving Dexamethasone injection 5 mg and then slowing down injection speed. RE-SULTS:Physicians adopted the suggestions of clinical pharmacists. Allergic reaction relieved 5 min after giving Dexamethasone in-jection. The patient didn't suffered from this allergic reaction again under tight supervision. CONCLUSIONS:Oxaliplatin is often used for tumor therapy. Medical staff should be familiar with the prevention,diagnosis and treatment of ADR,evaluate oxaliplatin chemotherapy plan in advance and screen high risk allergy factor. The participation of clinical pharmacists in pharmaceutical care contribute to ADR monitoring and promote safe and rational drug use in the clinic.

OBJECTIVE: To discuss the method and effect of exercising larynx and genioglossus to treat obstructive sleep apnea hypopnea syndrome (OSAHS). METHOD: Fifty-four patients who were diagnosed as OSAHS and exercised larynx and genioglossus were defined as treatment group. We took Epworth sleep scale, check patient's PSG, and took computer tomography (320CT) before treatment, 6 months and 12 months later. We made a record of AHI, LSaO2, BMI, the shortest sagittal diameter and transverse diameter. Compared with 30 patients who had taken UPPP surgery (control group 1) and the 21 patients without any treatment (control group 2) at the same time. SPSS 10.0 was used to analyze the data. RESULT: According to Chinese OSAHS construction in 2009, 6 months and 12 months later, the effective rates of treatment group were 31.48% and 44.44%, among which the effective rates in mild and moderate patients of treatment group were 44.74% and 63.16%. Before treatment the mark of Epworth sleep scale was 7.67, 6 month and 12 month later the marks were 3.54 and 3.25. AHI were up to 15.45 after 6 months and 13. 60 after 12 months from 22. 84 at the beginning. LSaO2 were up to 81.18% after 6 months and 81.93% after 12 months from 74.05% at the beginning. The effective rate of control group 1 was 66.67%, and was much higher than the treatment group 6 months later (P < 0.05). But there was no statistics difference of effective rate between treatment group and control group 1 (36.67%) after 12 months (P > 0.05). The effective rates of treatment group were much higher than control group 2 (P < 0.01). After 12 months, the sagittal wall compliance of retropalatal area was lower (P < 0.01). There was no significant change of BMI in every group. CONCLUSION Exercising larynx and genioglossus is one kind of non-invasive and effective method without payment to treat part of OSAHS patients, especially the patients who is old, without surgical condition, and especially mild and moderate OSAHS patient that do not want to take surgery and CPAP treatment. Besides, exercising larynx and genioglossus can be considered as remedial treatment of OSAHS to surgery and other therapy.

OBJECTIVE: To evaluate diagnostic significance of the noninvasive and objective 320-slice CT scan in the high pharynx resilience in the patients with obstructive sleep apnea/hypopnea syndrome. METHOD: Fifty patients with OSAHS and 10 patients with pharyngeal paraesthesia were included in the study. 320 slice CT scan was used to measure the sagittal diameters, transverse diameters and sectional area of the retropalatal region, retroglossal region. Calculating the pharynx wall resilience. Analyzing the correlativity of pharynx wall resilience, BMI and AHI. Fiber endoscope was used to assess the subsidence percentage of the pharynx wall. RESULT: Between OSAHS patients and pharyngeal paraesthesia patients, there was obviously difference in the retropalatal region and retroglossal region upper airway. The pharynx wall resiliences of retropalatal region were much more than that of retroglossal region. The later pharynx wall resiliences were much more than the fore-to-aft pharynx wall resiliences in the retropalatal region. BMI, AHI and the pharynx wall resilience were positive correlative to each other. But AHI and the pharynx wall resilience was nonlinear correlative. There was a good concordance between the pharynx wall resilience detected by 320CT and subsidence percentage of the pharynx wall detected by fiber endoscope. CONCLUSION 320 slice CT is a kind of simple, rapid and objective method to localize the high resilience area of upper respiratory tract, which can be benefit to the clinical diagnosis, the etiological study and the treatment of OSAHS. Based on physical examination, we propose that only one time of CT scan to the patients' upper airway at the Muller' stage is enough to localize the stenosis area, which can reduce radiation dosage dramatically.
